The relevant Inrap regional office obtains from the developer essential information about the development project (topographical data, useful technical information). It chooses the members of the archaeological team and organises the necessary technical backup (hydraulic diggers, site huts.)
In addition, the site director of Inrap, designated by the Regional Archaeology Service (DRAC) consults the Sites and Monuments record held by this body so as to have all the available information on the archaeological deposits in the area.
